The invention provides a vehicle crawling method and device, a vehicle and a storage medium, the method is applied to the vehicle, and the method comprises the steps that whether the current stroke of a brake pedal is smaller than a preset stroke where braking force is not generated or not is detected; if it is detected that the current travel is smaller than the preset travel, activating a crawling function of the vehicle, and determining a target crawling speed of the vehicle based on the current travel; and controlling the vehicle to execute the creeping action according to the target creeping speed. According to the method, the brake pedal stroke signal can be used for replacing a main cylinder pressure signal, when the brake pedal stroke is smaller than the preset stroke where braking force is not generated, the creeping function of the vehicle is activated, the vehicle is controlled to creeping at the target creeping speed, no braking force is involved in the vehicle creeping process, the creeping torque is reduced, energy consumption is reduced, and the service life of the vehicle is prolonged. And meanwhile, unnecessary friction plate abrasion is also reduced.

    本申请提供了车辆蠕行方法、装置、车辆及存储介质,该方法应用于车辆,该方法包括:检测制动踏板的当前行程是否小于不产生制动力的预设行程;若检测到当前行程小于预设行程,则激活车辆的蠕行功能,并基于当前行程确定车辆的目标蠕行车速;按照目标蠕行车速控制车辆执行蠕行动作。该方法能够利用制动踏板行程信号替代主缸压力信号,在制动踏板行程小于不产生制动力的预设行程,激活车辆的蠕行功能,控制车辆以目标蠕行车速蠕行,在车辆蠕行时无制动力介入,降低了蠕行扭矩,减少了能源消耗,同时也减少了不必要的摩擦片磨损。
